Demonstration of the infinite exponential mixture model with data sets discussed in Landowne et al. (44). “Boliden 3” corresponds to a mixture of four exponentials where each component has a higher timescale parameter and larger weight. “Boliden 4” is a mixture of four exponentials where one of the components has smaller weight than the adjacent components. Using the parameter values reported in Landowne et al. (44), 10⁴ data points are drawn from each mixture and analyzed using the infinite model. We are able to correctly recover the number of components and the relevant parameters. Algorithm parameters: α = 1.
